gap-size

Arguments:
multi-picture-button

Returns (or sets with setf)
the value of the gap-size property of a multi-picture-button
control. This value is the extra pixel-width that is allotted for a
gap between certain buttons of a multi-picture-button. (A gap appears
wherever the keyword symbol :gap is included within
the list of button-info objects in the
multi-picture-button's range.)

The default value is 8. The value of the spacing property, which determines
the general spacing between buttons, is added to the gap-size to find the total spacing
between two buttons that have a gap between them.

A separator bar (a vertical line) is also drawn when the value of the
multi-picture-button control's
button-3d-border
property is :when-pressed. If a separator bar is
drawn in the gap, it is drawn in the middle of the gap area.
